SUVLKY-HARROW.

SPECIFICATION forming part of Letters Patent No. 345,603, dated July 13,1886.

Application filed March 4, 1886.

of the United States of America, residing at Severance, in the county ofDoniphan and State of Kansas, have invented certain new and usefulImprovements in Sulky-Harrows; and I do hereby declare the following tobe a full, clear, and exact description of the inven-' tion, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to certain new and use ful improvements in wheeledharrows, the object of the same being to provide a meanswhereby thebarrow-frames can be forced into the ground and elevated when desiredfor transportation; and to this end my invention consists in the specialconstruction and combination of the parts, as will be hereinafter fullyset forth, and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 isa plan view of a sulky-harrow constructed in accordance with myimprovement. Fig. 2 is a longitudinal section; Fig. '3, a rear view, andFig. 4 a detail perspective view.

A A refer to the supporting-wheels, which are provided with a broadtread or tire. The axle Bis bent upward centrally, the upwardlyextending portions being indicated by the letters ff, which areconnected to each other by a transverse horizontal portion, f, to whichthe draft-tongue D is bolted.

To the rear upper portion of the draft-tongue D, immediately above thehorizontal portion of the axle, the drivers seat is secured, and infront of said seat the tongue is provided with a crossbar, D, to whichthe whiffletrees are attached. The horizontal portion f of the axleadjacent to each side of the tongue has secured thereto bearings d d,within which is journaled a bar, F, which is centrally provided with adownwardly-projecting arm, 6, having a hooked end, 6, with which engagechains E E, which diverge from this hook,

, and are secured to the outer bars of the har- Scrial No. 194,054. (Nomodel.)

row-section. The end of the pivoted bar F has secured thereto anoperating-1ever, F, which extends upward, so as to be within convenientreach of the driver.

G G refer to longitudinal beams, which are rigidly bolted to thevertical members f of the axle B, these bars being connected to eachother adjacent to their rear ends by means of a transverse bar, 9, whichtransverse bar passes through and forms a pivotal support for the rearend of a lever, 0, said lever being centrally supported and preventedfrom falling by a'chain, '0, as will be hereinafter set forth. The barsG G, near their forward and rear ends, are provided with hooks h h, fromwhich depend chains or flexible connections H H, which are secured tothe outer bars of the barrow-sections, said chains being of such alength that they will permit the harrow-sections to rest normally nearthe surface of the ground.

I I refer to the barrow-sections, which consist of longitudinal beamswhich are suitably connected to each other, said beams being provided ontheir under sides with projecting teeth, which converge alternately, asshown in Fig. 3. These harrowsections are provided with staples i i,with which the chains H engage, and centrally with staples z", to whichthe ends of the chains E E are secured.

The harrow-sections I I, hereinbefore referred to, are connected to eachother on their inner sides by bent spring-bars J, the ends of which areupturned, so as to engage with staples j, which enter the upper edges ofthe inner beams of the harrow-sections. This bent spring-bar J normallyexerts an outward spring-pressure, while its movement inward is limitedby a spiral spring, j, which is located on a bar and bears against theinner sides of the springs J.

K K refer to-two bars, which are pivotally secured to the outer sides ofthe barrow-sections, said bars being pivoted to each other at theirupper ends, as shown at It. The lower portions of these convergingspring-bars K are encircled-by spiral springs K, above which are locatedsliding collars l, to which the short chain, which extends under thelever O, is secured.

The operation of my invention is as follows: Vhen the parts areorganized as shown in the accompanying drawings, the implement is readyfor use, and the harrow-tceth will enter the ground for a sufficientdistance to pulverize the soil. Should the soil in certain places bemore compact than the average surface of the field, the llarrowsectionsmay be depressed by bearing down upon the end of the lever or bar 0, soas to cause said lever to depress the short chain c and upon thebarrow-sections, thus causing said harrowsections to enter the ground toa greater depth than would be caused by their weight alone, it beingunderstood that the chains II are sufficiently slack for this purpose.The spring-bar .I, in connection with the spiral spring K, will have atendency to keep the barrow-sections I on the same plane with eachother, and at the same time will allow said harrow-seetions to assumedifferent angles in accordance with the inequalities of the ground.

Vhen it is desired to elevate the harrowsections, thelever F can bedepressed, so as to elevate the bar 0, which will carry with it thechains E, which movement will cause the barrow-sections to be elevatedand will tilt the outer ends upwardly.

I claim 1. In a wheeled barrow, the combination,

press the spiral springs K,

l l I i l l l l l i l l l l with a bent axle, of a draft-tongue, anopelr ended frame, G, secured thereto, harrow-sections I I, connectedcentrally to each other and to the open-ended frame by chains II, and alever, O, pivoted to the open-ended frame and adapted to contact with achain for pressing springs which encircle the converging bars K K, theparts being organized substantially as shown, and for the purpose setforth.

2. The barrow-sections I I, connected to a wheeled frame, substantiallyas described, and provided at their inner sides with bcntspringbars Jand spiral springs j, substantially shown, and for the purpose setforth.

3. In combination with a wheeled barrow constructed substantially asdescribed, the independent harrow-sections I I, connected to each otherby spring-bars, the converging bars K K, pivoted to each other and totheharrowsections, and provided with springs K, sliding collars Z,flexibly connected to each other, and a lever, C, for compressing saidspiral springs, the parts being organized substantially as shown, andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
